ObjectiveTo explore the potential mechanism of Shenqi Jianxin Formula （参芪健心方） in the treatment of chronic heart failure （CHF） from the perspective of regulating mitochondrial autophagy via the PTEN-induced kinase 1 （PINK1）/E3 ubiquitin ligase （Parkin） pathway. MethodsMale SD rats were subjected to abdominal aortic constriction to establish the CHF model. Twenty-four successfully modeled rats were randomly divided into the model group， sacubitril/valsartan group， and low- and high-dose Shenqi Jianxin Formula groups， with 6 rats in each group. Six other rats were set as the sham surgery group， which were only separated the abdominal aorta and then closed the abdomen. Rats in the low-dose and high-dose Shenqi Jianxin Formula groups were given intragastric administration of Shenqi Jianxin Formula suspension at doses of 4.41 g/（kg·d） and 17.64 g/（kg·d）， respectively； the sacubitril/valsartan group received intragastric administration of sacubitril/valsartan sodium tablet suspension at 10 mg/（kg·d）； the sham surgery group and the model group were given normal saline at 10 ml/（kg·d） via intragastric gavage. The intervention lasted for 4 consecutive weeks. Cardiac function indices including left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） were detected， and serum brain natriuretic peptide （BNP） content was measured. HE staining and Masson staining were used to observe myocardial histopathological changes. Transmission electron microscopy was employed to examine the ultrastructure of cardiac tissues. Quantitative real-time polymerase chain reaction （Rt-qPCR） was performed to determine the mRNA expressions of PINK1/Parkin pathway-related factors and autophagy-associated proteins including Beclin-1， p62， and microtubule-associated protein 1 light chain 3 （LC3） in myocardial tissues. ResultsCompared with the sham surgery group， the model group showed significant decreases in LVEF and LVFS levels， an increase in serum BNP content， down-regulated mRNA and protein expressions of PINK1， Parkin and Beclin-1 in cardiac tissues， up-regulated mRNA and protein expressions of p62， as well as significant reductions in LC3B mRNA expression， phosphorylated PTEN-induced kinase 1 （p-PINK1） and phosphorylated E3 ubiquitin ligase （p-Parkin） protein levels， and the ratio of microtubule-associated protein 1 light chain 3-Ⅱ to microtubule-associated protein 1 light chain 3-Ⅰ （LC3Ⅱ/LC3Ⅰ） （P＜0.05）. Pathological results revealed obvious myocardial cell edema， necrosis and degeneration， increased disorder of myocardial fiber arrangement， extensive inflammatory cell infiltration， moderate to severe mitochondrial swelling， a few mitochondrial vacuolar changes， and no obvious autophagy in the field of vision in the model group. Compared with the model group， all the above indicators were significantly improved in the high-dose Shenqi Jianxin Formula group and the sacubitril/valsartan group （P＜0.05）. Moreover， the improvement of each index in the high-dose Shenqi Jianxin Formula group was superior to that in the low-dose group （P＜0.05）. In the high-dose Shenqi Jianxin Formula group， myocardial myofibrils were arranged regularly with orderly orientation， the striated structure was clear， and necrotic cells significantly reduced. ConclusionShenqi Jianxin Formula can activate the PINK1/Parkin signaling pathway in myocardial tissues， enhance mitochondrial autophagy， and clear dysfunctional mitochondria， thereby improving cardiac function and delaying the progression of CHF.

Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

Objective:To explore the hearing changes of children with different genotypes of SLC26A4 with enlarged vestibular aqueduct（EVA） using the linear mixed effect model（LMM）, providing evidence for the risk prediction of progressive hearing loss. Methods:A total of 48 children with EVA diagnosed in our hospital from January 2017 to January 2024. All subjects underwent two or more auditory tests. According to the results of deafness gene screening and sequencing, the genotypes are divided into: type A: homozygous mutation of c. 919-2A>G, type B: compound heterozygous or heterozygous mutation containing c. 919-2A>G, and type C: no mutation site of c. 919-2A>G of SLC26A4 gene. LMM was used to analyze the hearing thresholds change of 500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz and the average in children with different genotypes with age. Results:A total of 92 ears, 314 audiograms of 48 children were included, the median number of audiograms was 3, the median age of initial diagnosis was 4 months, and the median follow-up time was 13 months. According to LMM, the standard deviation of random effects between patients and ears was large. There was no significant difference in hearing thresholds of different frequencies and the average in genotype A, genotype B, and genotype C, indicating that genotype had no effect on hearing threshold. There is an interaction between age and genotype. Taking genotype C as the reference, children with genotype B had the lowest increase in 500 Hz, 1000 Hz, and the average hearing threshold, followed by type A. Conclusion:EVA children exhibit substantial inter-individual/ear hearing threshold variability. Low-frequency thresholds progress slower than high frequencies. Genotype modulates progression rates, with wild-type（Type C） demonstrating fastest deterioration, supporting personalized auditory monitoring strategies.

Objective To evaluate early outcomes of transthoracic pulmonary valve implantation for the treatment of moderate and severe pulmonary regurgitation by using homemade self-expanding valve (SalusTM). Methods Patients with severe pulmonary regurgitation who underwent transthoracic pulmonary valve implantation in Guangdong Provincial People’s Hospital from September 2, 2021 to November 25, 2022 were prospectively enrolled. The early postoperative complications and improvement of valve and heart function were summarized and analyzed. Results A total of 25 patients were enrolled, including 16 males and 9 females, with an average age of 24.5±1.5 years and an average weight of 57.0±3.0 kg. The mean systolic diameters of the bifurcation near the main pulmonary artery, the stenosis of the middle segment of the aorta and near the valve of the right ventricular outflow tract of the patients were 31.8±7.4 mm, 30.6±5.9 mm and 38.4±8.0 mm, respectively. All patients were successfully implanted with valves, and there were no serious complications such as death, coronary compression, stent fracture, valve displacement and infective endocarditis in the early postoperative period. The indexed left atrial longitudinal diameter, indexed right atrial longitudinal diameter, and indexed right ventricular outflow tract anteroposterior diameter decreased significantly after the operation. The degree of tricuspid and pulmonary valve regurgitation and the indexed regurgitation area decreased significantly. The above differences were statistically significant (P<0.05). Conclusion The early outcomes of transthoracic pulmonary valve implantation with homemade self-expanding pulmonary valve (SalusTM) in the treatment of severe pulmonary regurgitation is relatively good, and the long-term outcomes need to be verified by the long-term follow-up studies with large samples.

Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.

OBJECTIVE To analyze the difference of genotypes and hearing phenotypes in infants with biallelic allele variant in GJB2,and to provide reference for clinical practice. METHODS One hundred and forty-two subjects with biallelic allele variant in GJB2 were recruited in Beijing Tongren Hospital from August 2012 to March 2024. All subjects received universal newborn hearing screening(UNHS),neonatal deafness genetic screening and audiological tests. The subjects were divided into three groups according to the genotypes:T/T groups(truncated/truncated mutations,59 cases),T/NT group(truncated/non-truncated mutations,50 cases) and NT/NT group(non-truncated/non-truncated mutations,33 cases). Three groups of genotypes,newborn hearing screening results,age at first diagnosis and hearing diagnosis results were analyzed. RESULTS The homozygous mutation of c.235delC/c.235delC was the dominant in T/T group(57.63％),the compound heterozygous mutation of c.235delC/c.109G>A was the dominant in T/NT group(74.00％),and the homozygous mutation of c.109G>A/c.109G>A was the dominant in NT/NT group(96.97％). The overall refer rate of UNHS was 80.28％,and the refer rate of T/T group was 89.83％,which was significantly higher than that of T/NT group 70.00％(P=0.009). The age of first diagnosis of 142 cases was (3.70±1.56) months,there was no significant difference between the three groups(P>0.05). In 142 cases,104 cases with hearing loss accounted for 73.24％,38 cases with normal hearing accounted for 26.76％. The proportion of confirmed hearing loss in T/T group was 100.00％,which was significantly higher than that in T/NT group 52.00％(P<0.001) and NT/NT group 57.58％(P<0.001). In side of hearing loss,of the 104 patients with hearing loss,86 cases(82.69％) had bilateral hearing loss and 18 cases(17.31％) had unilateral hearing loss. The proportion of bilateral hearing loss in T/T group was 100.00％,which was significantly higher than that in T/NT group 57.69％(P<0.001) and NT/NT group 63.16％(P<0.001). Among 190 ears of 104 patients with hearing loss,the degree of hearing loss was predominantly mild to moderate(63.16％),followed by profound(24.74％) and severe(12.10％). Among them,the T/T group was mainly marked by severe to profound hearing loss(58.47％),while both the T/NT group and the NT/NT group were mainly characterized by mild hearing loss(58.54％ and 74.19％),and the differences among the three groups were statistically significant(P<0.001). CONCLUSION In the T/T group,all patients were diagnosed as bilateral hearing loss at first diagnosis,and was mainly severe and profound hearing loss. The bilateral and unilateral hearing loss were 52.00％ and 57.58％ in the T/NT group and NT/NT group at first diagnosis respectively,and was mainly mild hearing loss.
